Retrofitting wiring harness of CD changer - AZ82.64-P-0001-01G

Model 210.2 as of 1.7.98 with code 317, 813b except code 351 

1. Check fiber optic cable routing in load compartment on right and note components connected in D2B ring.

   The maximum component sequence is:

   • Radio (A2)
   • CD changer (A2/6)
   • Voice control module (A35/11)
   • CTEL interface (A34/4)
   • Radio (A2).

   If a component is not installed its position in the maximum sequence is eliminated and resulting in a new sequence. This allows determination of the route for the fiber optic cables in the vehicle.

2. Remove red insert (rt) from the fiber optic cable module M1 coming from the radio (A2) from the connector on the control module for voice control (A35/11) or on the CTEL interface (A34/4) (corresponding to components installed in vehicle) and insert into new connector housing.
3. Insert new fiber optic cable module M2 with white insert (ws) into new connector housing and lock housing.

   The fiber optic cable module M2 must be long enough to connect the CD changer (A2/6) to the next D2B ring component.

   Observe special routing guidelines for fiber optic cables.
